Synthesis, crystal structure and magnetic properties of a three-dimensional cyano-bridged heterometallic complex {NiII(Me6-[14]ane-N4)}2[WIV(CN)8]·6H2O

“…The mean W-C and C-N distances are 2.158 Å and 1.138 Å , respectively. The bridging CN ligands exhibit almost linear W-C-N units with the angles ranging from 172.8(4)°t o 179.0(5)°and significantly bent Ni-N-C sequences (151.3(4)°and 158.4(4)°for Ni1-N1-C1 and Ni2-N2-C2, respectively, which are typical for cyano-bridged octacyanides [16][17][18][19][20][21]). …”

Towards Rational Syntheses of the Elusive Metallocarbohedrenes: Density Functional Prescriptions for Electronic and Geometric Structures

“…[45] Attention is drawn to [( i Mn À CH 3 ) 4 (C 2 ) 6 ( o Mn À CH 3 )] 0 S 7, [( i Fe) 4 (C 2 ) 6 ( o Fe À Cp)] 0 S 8, [( i FeÀCl) 4 (C 2 ) 6 ( o CoÀCl)] 0 S 7 and [( i Ni) 4 (C 2 ) 6 -( o CoÀCO)] 0 S 8. There are similarities between these metallocarbohedrene molecules and some recently reported very high-spin polycyanometallate molecular clusters such as [Mn{Mn(MeOH) 3 } 8 (m-CN) 30 {Mo(CN) 3 } 6 ], [46] [(Me 3 tacn) 8 -Cr 8 Ni 6 (CN) 24 ] 12 , [47] and [Cr 8 Ni 5 (CN) 24 ] and [Cr 10 Ni 9 (CN) 42 ] [48] clusters in crystals.…”

Synthesis and Crystal Structure of a Cyanido-Bridged Bimetallic Copper(II)–Silver(I) Complex of Imidazole and [Ag(CN)2]−: [Cu(Imidazole)4{Ag(CN)2}2]

“…The synthesis of cyanido-bridged bimetallic coordination polymers has been of great interest in recent years [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] because of their interesting topological structures and, their magnetic, electrochemical, magneto-optical, ion exchanging and catalytic properties [16][17][18][19][20][21][22][23]. Cyanidometallates, such as [Fe(CN) 6 ] -3 [3,8,9,24], [Ni(CN) 4 ] -2 , [4-6, 15, 16, 25-27], [Pd(CN) 4 ] -2 [12,13,18], [Au(CN) 2 ] - [14,[28][29][30][31][32] and [Ag(CN) 2 ] -[2, 10, [33][34][35][36][37][38][39][40]…”
